Add weather to the equation and his department has been busy. Cohn said the S curve stretch of road is dangerous for drivers and first responders. Last month, one of their SUVs was rear-ended after being called to help.

“We ended having five vehicles in a crash of one vehicle off the roadway,” Cohn said.

Before all of that, Cohn got the Greenfield Fire Department, the Police Department, the Milwaukee County Sheriff's Office and the Department of Transportation to the table to discuss why he believed crashes were happening more frequently.

“I think people somewhat knew the data that was coming out of this stretch, but until you sit down and really look at it, it gets merged in with the data from the freeway system,” Cohn said.

Information from the Sheriff's Office confirmed higher crash numbers between 124th Street and Layton Avenue. In 2013, there were 45 total crashes. In 2014, there were 68, and so far this year, there have been 72 through Oct. 28.

“We've had three vehicles in the last three years make it to the water,” Cohn said.

One of the most notable crashes was back in May. A woman slid off the road, through a fence and into the pond near Whitnall High School.

“My girlfriend's yelling at me to look up, and I see the car, you know, losing control and going off the road and into the pond,” witness Jake Saxton said.

Saxton saw it happen and stopped to help her to safety.

Cohn said he's hoping for no more water rescues.

“Do we expect crashes to go down to zero? Hopefully, but if we can make it safer, I think that's our goal,” Cohn said.

The DOT said it will apply a new high-friction surface treatment, and instead of the fence that was in place, guardrails will be installed.
